David Oyelowo plays a mild-mannered Nigerian working for a pharmaceutical company which has invented a marijuana pill. Hilarity and bloodshed ensue when his shady bosses (Charlize Theron, in man-eater mode; Joel Edgerton, in douchebag mode) implicate him in a conspiracy involving the Mexican drug cartel.

Oyelowo is a serious actor who’s been in a few serious movies (Selma, A United Kingdom), so it’s kinda refreshing, odd even, to see his sillier side in this sporadically diverting, tonally uneven crime caper. Sharlto Copley shines too as a reformed mercenary hired to defuse the situation, but his story belongs in another movie. (**1/2)
